Google suggest tool is the latest improvement by Google to enhance the searching experience of users. Basically what it does is when you start typing certain words in the search field it gives some suggestions based upon the search volume for that certain words you have typed. For example if you type make money in the search field you are given with a list of suggestion like make money from home , make money online , make money with Google etc. What is important to note is that beside all of these suggestion the search volume for each word combination is displayed. And that's where the real power of Google suggest tool kicks in.

Lets take my last post ,  HTML code to add a favicon as an example. It is about adding a favicon to your blog or website. So the obvious title should be how to add a favicon to your blog , but the google suggest tool search volume shows that it has around 2,420,000 search queries. but queries like favicon html and favicon code has much higher search volume so adding those keywords in the title should give your more traffic. add those keywords in the body of the post as well and you are likely to get more traffic through this method.
